Question

SEPARATE THE FOLLOWING MIXTURES AND WRITE THE PROCEDURE

a. Sand and water

b. Collect sand and separate iron filings using a magnet.

c. Oil and water.​

Answer 1

Answer:

1. Sand and water can be separated by any of the following two methods: (a) Sedimentation and decantation: Mixture is kept undisturbed for some time. After some time, sand being heavier and insoluble in water, settles down at the bottom of container. Now, water is poured into another container to separate it from sand.
2. Water Soluble
4. Iron is magnetic and the other two not, which means a magnet could be used to attract the iron filings out of the mixture, leaving the salt and sand. Salt is water soluble, while sand is not. This means the two can be mixed in water and stirred. The salt will dissolve and the sand will not.
5. Two immiscible liquids, oil and water, can be separated by using Separating Funnel. The process involves using the mixtures of unequal particle density. Because water is denser than oil, it can be separated by means of the funnel and left in the funnel with an oil layer.
